The planning and design of road network structure in urban railway transit hub areas

摘要

Urban railway transit has developed rapidly with the acceleration of urbanization in recent years. Railway transit hub as an important part of urban railway transit has great impacts on urban traffic system. But there are severe traffic problems in road network due to the complex traffic characteristics of urban railway transit hub areas. To solve the traffic problems in network structure in urban railway transit hub areas, this study first investigated the mechanism mode of road network, then determined the influence scope of road network in Tianjin loop hub areas based on TOD mode and land utilization in the hub areas, proposed corresponding planning and design, performed adaptability assessment on facilities in the traffic hub areas, and finally summarized the road network mode which was suitable for Tianjin urban railway traffic. It was concluded that the mode could relieve central urban traffic pressure, which can provide a reference for the promotion of urban integrated traffic network.
